Because body temperature can be a really good indicator of low thyroid function (or high thyroid function), many people who begin taking their basal body temperature daily notice that they may have a bit of a thyroid issue, which many people do have, undiagnosed.
Shomon’s book is intended to disseminate information that she researched for herself when diagnosed with a thyroid problem, and also to wake people up to the prevalence of hypothyroidism, push for better screening/tests, and to control your thyroid enough to live well. She includes five parts on 1.) symptoms, diagnosis, and treatment 2.) Conventional and alternative treatment options 3.) Challenges and controversies 4.) Special concerns of hypothyroidism 5.) Living well now and in the future.
Shomon offers wonderful tips on how to get tested, what numbers you should be looking for in your tests (since many labs have different values), how to find thyroid replacement that works for you, how often to check your thyroid levels, and many other life concerns of those who are hypothyroid (such as infertility!).
Overall, I think this book is a valuable read for those who have some symptoms of hypothyroid and are finding that their temperatures are in the low range. Perhaps adopting a few lifestyle tips could be enough to support your thyroid or perhaps you may need to take thyroid hormone, but this book will help with either option.
